The origin of purine and pyrimidine deoxyribose in T6r+ bacteriophage.
Lanning and Cohen (1) reported that when Escherichia coli strain B is infected with T6r+ bacteriophage in a medium containing glucose-1-Cr4, the deoxyribose from the deoxyribonucleic acid of the T6rf particles liberated on lysis of the cells contains 40 to 60 per cent of the specific activity of the exogenous glucose. In parallel experiments, it was shown that the deoxyribose from the deoxyribo...
متن کاملthe analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولProtonated pyrimidine-purine-purine triplex
We have studied a protonated pyrimidine-purine-purine (Py-Pu-Pu) triplex, which is formed between the d(C)nd(G)n duplex and the d(AG)m oligonucleotide as the third strand and carries the CG*A+ protonated base-triads. We have observed such an intermolecular complex between a plasmid carrying the d(C)18 d(G)18 insert and the d(AG)5 oligonucleotide without bivalent cations in 200 mM of Na+ at pH4....
متن کاملPurine and pyrimidine metabolism.
The pathways of purine biosynthesis and degradation have been elucidated during the last 30 years; the regulation of the mechanisms involved is not yet fully understood, particularly with respect to quantitative aspects. Research into inborn errors of purine metabolism has provided valuable insights into purine synthesis and salvage pathways. Nutrition experiments using purine-free formula diet...
متن کاملSome precursors of the 5-hydroxymethylcytosine of T6r+ bacteriophage.
A new pyrimidine, 5-hydroxymethylcytosine (HMC) (1, 2), has been isolated from bacterial viruses of the T even type, which multiply in Escherichia coli. Deoxyriboside (3) and deoxyribotide (4) derivatives from this source have also been described. These components are not present in appreciable quantities in the nucleic acids of E. coli or of other cells, or in any other virus analyzed to date....
